EOS Indication

EOS device status is defined as 3 months following an RRT indication assuming the following PSP conditions: 100% VVI pacing at 60 min-1, 2.5 V, 0.4 ms; 500 Ohm pacing load; and 6 full-energy charges. EOS may be indicated before the end of 3 months if the device exceeds these conditions.
